In 2006 Knox, a British manufacturer of impact protection for use in extreme sports, patented the SPS (scaphoid protection system). Designed for motorcyclists, SPS offers protection against common scaphoid injuries caused either by a compression fracture or by hyper extension when a glove palm made contact with the road. SPS consists of two low-friction pads positioned on the palm of each glove designed to eliminate the ‘grab’ effect and allowing the hand to slide.[5] In 2012 Knox introduced SPS for mountain biking and cycling applications too. SPS has been adopted by many brands of motorcycle glove[6]
